WEATHER STRIP.

Application filed November-2, 1922. Serial No. 598,536.

To all'whom it may cancem:

Be it known that I, JosIiPH G. DUNHAM, a citizen of theUnited States, residing at Oklahoma Cit in the county of Oklahoma and State of Oklahoma, have invented a certain new and useful Improvement in Weather Strips, of which the following is a specification, reference being had to the accompanying drawings.

The invention provides simple and effective means in the way of a weather-strip of novel construction for preventing the pas sage of air, dust, water and other substances between the Window-sash and the windowframe, and for the easy'and quick removal of the lower sash and said 'Weather Strip from the frame.

Another object of the invention is to provide means for securely holding the window or other enclosure in place in any and all kinds of weather, taking up the play between v the sash and the frame caused by shrinkage,

and also allowing for their expansion caused by swelling.

The invention, novel features, details of construction and combination of parts will be hereinafter more particularly set forth,

illustrated in the accompanying two pages of drawings, and pointed out in the appended claims.

- Referring to the drawings forming a part of this application,

Figure 1 is an elevational view of the inside of the upper and lower sash and the in side view of the window-frame surrounding them, installed with a weather-strip, show-. ililw cross-section lines AA, 13-13 and FigureQ is a sectionalview ofa portion of thetop cross-section of the window-frame above the upper sash,and a portion of theupper sash shown on a line A-A as shown in Figure 1, and showing as viewed horizontally.

F gure 6 is a pers ective view of a port1on of the sill, a P01131011: of the amb, a portion of the lower sash, a front -stop with screws holding the sash in place, and the Figure 9 isa sectional view of a portion of the jambopposite the upper sash, and-a portion of the side of said sash, and the weather-strip, and the sheet metal spring a Figure 10 is a perspective view of a portion of the upper sash showing a hole thereer-strip showing a bulged raised portion in the said strip to fit into said hole when said sash is fully raised.

' in near the top, and a portion of the weath- I Like characters" of reference designate like parts in all the figures.

The window shown in Figure 1' has the usual 'partszsill, jambs and lintel,and includes the inner casing or frame 1, the upper sash 2, the lower sash 3, the front-stop 4,. and screws 5 holding it in place. Theimproved weather-strip 6 is of sheet metal, for example sheet brass, or sheet bronze, or other sheet metal of good sprin quality; or 'it may be made of sheet zinc], an when so made, may be used alone, or'it may have a curved or bent strip 16 ofisheet brass,

sheet bronze, or other sheet metal of good spring quality back of said sheet zinc strip 6, the whole length thereof, or shorter strips of said curved or bent sheet metal may be attached to said jamb in back of said sheet weather-strip. Near one end is shown a por- 15 the metal in said strip is curved or cupped tion of the strip curved up at right angles with the body of said strip as shown at the nail 8 Figure 5, and on the opposite side of the body of the strip from the window-sash, said carved end being insertedinto a small groove 13 in the jamb. In the lintel and the sill similar-strips are preferably held in place by nails 8 or other permanent securing members, disposed near the curved or flange ends and passed through said strips into the frame; and each strip has a flat portion or body bent slightly away from said jamb and toward the sash and ending in a shoulder 14 and between said shoulder 14 and shoulder oppositely to said first mentioned curved end, soas to form a loop 10 fitting into a larger groove 11 in said sash; from said shoulder 15 to the beginning of the curved end 9 the strip extends substantially in a straight line; the other end 9 of said strip as distinguished from 7, is curved oppositely to said first end 7, and towards the sash and on the same side of said strip as said loop 10, and said end 9 fits into the smallergroove 12 in said sash.

Back of said weather-strip of sheet zinc,

when so made, and between said strip and the jamb; a short distance from said end 7 and nail 8 is placed a strip 16 of said sheet metal of good spring quality held in place in said jamb by nails 17 or other permanent holdin members, so as to force sald strip of sheet zinc into place against said sashand into the larger and smaller grooves, 11 and 12 in said sash. Instead of having the strip 16 running the full length of said weatherthe same way but at intervals of approxi strip and disposed in' back thereof, a series of similar, but shorter strips may be used in mately 12 inches apart, attached to the jamb backof said sheet zinc strip with nails 17 or other permanent holding members, and for the same purpose as ind1cated-to force the I said sheet zine weather-strip against the sash and the respective elements thereof into place into said;.larger and smaller grooves 11 and 12.- I

. Both jambs are preferably nip ed with the weather stripping-g describe as arealso' 9 the lintel and the the adjacentportion of the sashes being oved to receiye the respective portions'o the weather-strips.

jstrip so bent-as The lower sash 3 and the weather-strips 6 thereof are further held in place by a frontstop 4:, which is held in place by screws 5, orv

other permanent holding members.

As isshown in Figures 6, 7, and 8, by removin the screws 5 and the front-stop 4 and t e nails securing the weather-strips which co-act' with the lower sash, the sash and the weather-strip may be quickly and easily removed the better to adjust the weights or clean around said sash without havlng to mar the-frame and sash, and without bending out of shape the weather-strips. At 18 of Figure 10 is shown a holein-the uppersash near the top thereof, and in the upper portion of the said strip a bulged or raised portion of said strip opposite to said holeflin said sash when same is fully raised; the said bulged or raised rtion being in tended to fit into said hole in said sash when fully raisedso as to hold the said upper sash in place and in a closed position.

The preferred embodiment of the invention is disclosed in the drawings consisting of two pages, and set forth in the specifications, but it will be understood that any modification within the scope of the claimed inventlon maybe made in the construction without departing from the principle of the invention or sacrificing any of its advan turned down at right angles to the body of said strip, a portion near the other side edge turned up at right angles to the-body of said stri ,one of the edges fitting into a groove.

ermanent in t ejamb, said strip adjacent sai being secured to the jamb by holding members, the other edge tting into a groove in the sash, and said strip bent towards the sash and having a portion pressing against the sash.
